To me, steampunk and urban fantasy are naturally hinged together. And I think that's because I love the early gothic Victorian literature, and both things spring from that movement.
Technically and logically speaking, actual Victorian science fiction writers cannot be dubbed 'steampunks.' Although they utilized many of the same tropes and touchstones employed later by twenty-first-century writers of steampunk, in their contemporary hands these devices represented state-of-the-art speculation.
For every reader and writer of steampunk fiction, there are probably hundreds or thousands of other activists who gleefully embrace some non-written manifestation of the steampunk ethos.
The reason steampunk attracts people is that it is premised on a technology which is visible and pleasing to the naked eye, and whose moving parts are comprehensible on a human scale.
Steampunk, the repurposing of Victorian culture and technology for contemporary fun and profit, is so ubiquitous - in media, books, fashion, music, cosplay, and maker culture - that we tend to imagine its superficial aspects are all that define it.
The term 'steampunk' itself, now a badge of honor, began as a putdown, a joke. But like 'Big Bang' in cosmology, the diss became the standard.
Like steampunk, silkpunk is a blend of science fiction and fantasy. But while steampunk takes its inspiration from the chrome-brass-glass technology aesthetic of the Victorian era, silkpunk draws inspiration from East Asian antiquity.
Within the sphere of steampunk, there seems to be a rapidly growing subsphere of gadgetless 'neo-Victorian' novels, most of which attempt to recapture the romance of the era without all the sociopolitical ugliness.
I've really loved steampunk for a long time, ever since 'Wild Wild West,' and it's always been a genre and an era that's fascinated me. But so often it's set in England, and that doesn't really resonate with me, or maybe it just seems a little overdone.
I used to be very fascinated by Victorian stuff, and my best-known books, the 'Mortal Engines' series, have a sort of retro, Victorian vibe, despite being set in the far future.
There is a certain degree of 'steampunkishness' that creeps into my books.
